Love the bold flavours from using metal filters but hate the sludge? The ameuus o2 and o1 10K will help you brew a cleaner cup of coffee using the AeroPress.
We developed two types of filters to suit different brewing needs.
In addition to being eco friendly, metal filters allow coffee oil to seep through. The oil carries rich & bold flavours that are otherwise caught and lost when using paper filters.
The ameuus o2 provides the optimal filtration using a patent pending dual filtration design. Each of the a&b filter is jam-packed with ~50K holes!
With combined average hole size of 30 microns, you have the flexibility of using finer size coffee grounds for your favourite AeroPress recipe.
It's the small things that count.
The packaging of the o2 doubles as a carrying case. This increases shipping cost, but we thought it's important for you to be able to enjoy your o2 anywhere you go!
The case has enough room to fit many filters, so you can use it to store all your metal AeroPress filters!
Don't let the simplicity fool you, the ameuus o1 10K is perfect for those looking for a more traditional single filter design. Like the name suggests, it has 10K tiny 100 micron holes. It works great for medium coffee grind size!
The o1 10K is ideal for medium to coarse coffee grind setting.
Whereas the o2 gives you the ultimate flexibility for using different grind size settings. Although the plunge pressure does increase the finer grind size you go, so make sure you use a strong cup if you decide to use espresso grind.
Ever had trouble finding a place to dry your filters? The ameuus Drying Disc is a compact and portable drying stand that you can use to dry any AeroPress metal filters.
It's designed with 3 slots, so it can hold the o1, and the o2 at the same time!
If we hit our stretch goal, we can take the filter Drying Disc to production. And to celebrate hitting this goal, each backer of the o2 will receive the Drying Disc free of charge, with no additional shipping cost!
UPDATE: Since we hit our stretch goal, all o2 backs will receive the filter Drying Disc. You will not see this under the rewards listing, but don't worry we'll make sure it's included!
We've tested the o2 against some of the most popular filters on the market today. We purchased different filters on Amazon.com and compared the amount of sediments leftover after using the metal filters.
As you can see on the top, the ameuus filters clearly show less sediments when compared to the other two filters with the smallest hole size on the market today.
Our comparisons are for non-welded single construction metal filters (non-mesh).
To use the o2, simply match the "a" and "b" alignment guides found on the edge of the filters. Don't worry if you can't get a perfect match, a roughly aligned match will still brew a clean cup!
- Push AeroPress all the way down after brew
- Rinse cap with cold water
- Unscrew cap
- Slide the o2 filters out
- Rub the o2 against each other under running water
Graham is the 2018 Toronto Regional AeroPress Competition Champion. We were fortunate enough to have him, and other fellow competitors test out our filters.

Here's one of Graham's favorite AeroPress recipes using the ameuus o2.
- Grind: On a scale of 1-10: 3.5, size closer to kosher salt than table salt, but not as coarse
- Coffee: 22g
- Water: 200g
- Temp: 92°C/197°F
- Time: 4:00min
- AeroPress: Inverted

Take a piece of Toronto home with you. We created a precision etched metal bookmark, using the same material as the ameuus metal filters.
This reward is for those of you that may not want a metal filter, or do not have an AeroPress but would still like to support us. Reading a book never goes out of style!
It all started a year ago. Since then we've went through more than 20 variations of filter designs. After many failed prototypes, and hundreds of cups of coffee, we are excited to be able to share our creation with the Kickstarter and AeroPress community!
The ameuus micro filters are designed by Tecford Design from Toronto, Canada. Our team has over 20 years of collective experience designing and manufacturing micro-components.

Risks and challenges
Our team has extensive experience fulfilling products internationally, although there are always potential issues that could arise.
The biggest risk will be to ensure all products are delivered on time and undamaged. Due to the many different shipping intermediaries and customs differences in different countries, we may experience some challenges in accurately estimating the delivery time for all backers.
We will be sure to be transparent and provide updates frequently. From production, to packaging, to shipping, we'll keep you in the know!Learn about accountability on Kickstarter
